[font size=3]Scientists from UCLA's Fielding School of Public Health led by Julia Heck, an assistant researcher in the school's epidemiology department and a member of UCLA's Jonsson Comprehensive Cancer Center, have found a possible link between exposure to traffic-related air pollution and several childhood cancers.
For the study, the UCLA researchers utilized data on 3,950 children who were enrolled in the California Cancer Registry and who were born in the state between 1998 and 2007. They estimated the amount of local traffic the children had been exposed to using California LINE Source Dispersion Modeling, version 4 (CALINE4).
Pollution exposure was estimated for the area around each child's home for each trimester of their mother's pregnancy and during their first year of life. The estimates included information on gasoline and diesel vehicles within a 1,500-meter radius buffer, traffic volumes, roadway geometry, vehicle emission rates and weather. Cancer risk was estimated using a statistical analysis known as unconditional logistic regression.
The researchers found that heightened exposure to traffic-related air pollution was associated with increases in three rare types of childhood cancer: acute lymphoblastic leukemia (white blood cell cancer), germ-cell tumors (cancers of the testicles, ovaries and other organs) and retinoblastoma (eye cancer), particularly bilateral retinoblastoma, in which both eyes are affected.
